UNITED STATES PATENT OFFICE- GUSTAVE DOSSELMAN, OF CHICAGO, ILLINOIS, ASSIGNOR TO-ADAMS AND ELTING COMPANY,

OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

ONE-COAT SURFACE-FINISH.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed January 2, 1904. Serial No. 187,664.

To all whom it may concern:

Be it known that I, GUSTAVE DOSSELMAN, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new'and useful Improvement in One Coat Surface Finishes, and declare the following' to be a full, clear, and ergact description 0 the same, such as will enable others skilled in the art to which it ertains to make and use the same.

y invention relates in general to compositions of matter for finishing surfaces, and more particularly to a composition a single coat of which will produce upon the surface treated the desired finish.

In order to im art to a surface such finishes as mahogany; lemish, weathered oak, or golden oak, it has heretofore been customary to subject the surface to a series of treatments comprising, first, staining the surface the desired color, then scraping the surface, afterwards applying shellac and rubbing down the surface,

The primary object of my invention is to provide a composltion of matter consisting in such ingredients that a single coat thereof applied to a surface will impart thereto the desired finish, thereby reducing the labor and expense incident to the numerous steps hereto ore necessary to produce the finish. A further object of my invention is to provide a composition of matter simple in manufacture, and inexpensive in cost, and which may be readily a lied and produces an attractive and durable surface finish. 4

My invention, generally described, is a composition of matter consisting in a coloring ingredient, a solvent for the coloringingredient, abody ingredient which serves as the principal coating on the finished surface,

and an ingredient for uniting the coloring solution to the body ingredient. My improved composition may also contain an ingredient to retard the drying thereof so as to enable it to be smoothly spread over the treated sur-' face.-

In carrying out my invention I have fdund in practice that a coin )osition-ofmatter consisti in a pigment o the desired color dissolve in wood alcohol, .amylacetate collodion, and shellac, when applled to a surface imparts thereto an attractive appearance and at thesame time covers the same with a durable coating.

and finally applying wax.

While any desired relative proportions of the ingredients may be used, I have found in practice that good results may be produced by compounding one art of shellac to two parts of amylacetate co odion andadding a solution of wood alcohol cont ficient of color.

In lieu of dissolving a p' ment in methyl alcohol to impart the dos e color any other form of' coloring matter may be used, such as am lene or. other 'organic or chemical colors. In 'eu'of the amylacetate collodion may be employed benzole and a vegetable gum, but I prefer to use the amylacetate collodion that is gun cotton-dissolved in amylacet'aterather than an e uivalent ingredient such as suggested. T e amylacetate collodion or, its equivalent constitutes the body of the composition. and serves when the finish has been a plied to a surface, as the coating thereof, W ile the coloring solution gives to the coating the desired appearance. The shellac serves as a binder to unite the coloring solution to the amylacetate collodion. As an equivalent for shellac a gum'ma beused.

My improved composition 0 matteralso preferably contains an ingredient to retard the-d thereof so as to enable the same to be smoot y spread upon the treated surface. Such ingredient 1s preferably glycerin,

although "any variety .of waxmay be used in lieu thereof. The amount of glycerin to be. used should bevaried accordin to. the nature of the surface to be treated.v f a large surface is to be finished more glycerin should be used in order that the composition may be smoothly spread thereon than is necessary when the surface to be treated is small.

My composition of matter may be manufeatured by first dissolving the coloring matter in a solvent" such as methyl alcohol into which the shellac is poured and thoroughly mixed. The amylacetate collodion is then added and agitated so as to thoroughly inter mingle the ingredients. Glycerinor melted wax is finally added, if desired, to retard the drying of the composition. Other processes of com ounding the composition ma be followed but the foregoing'has been fl practice to be preferable.

und in A single coat of'a composition of matter I comprising the ingredients above specified or their equivalents applied to a surface produces a finish thereon which is not injured by either steam or water; and which by incor-- porating therein suitable coloring matter may bemade to resemble black or brown Flemish oak mahogany; brown or gray weathered oak; golden oak or colonial finish. I do not of course wish to limit myself either to the particular in edients specified, nor to the proportionsof t e ingredients, but desire to cover a composition of matter containing equivalents for the Various specified ingredients and of any relative proportions which may be found suitable for the various difierent surfaces to which my invention ma be applied.

aving now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. A composition of matter for finishing surfaces containing a coloring solution, amylacetate collodion, aningredient to unite the coloring solution to the amylacetate collodion, and glycerin.

2. A composition of. matter for finishing surfaces containin pigment, meth lalcohol, amylacetate collo ion, shellac, an glycerin.

In testimony whereof, I sign this specification in the presence of two witnesses.

. I GUSTAVE DOSSELMAN.
